Find the slope of the line that passes through (21, 15) and (90, 66).

17/23

Step-by-step explanation:

To find the slope of a line given 2 points, we use the formula

m = (y2-y1)/ (x2-x1)

    = (66-15)/(90-21)

    = 51/69

Divide the top and bottom by 3 to simplify the fraction

   = 17/23

0.74

Step-by-step explanation:

Slope is calculated as change in ydivided by change in x

= y2 - y1/x2 - x1

Step 1: Locate the coordinate points

From the question,

y2 = 66, y1= 15

x2 =90, x1 =21

Step 2:Then slot in the values into the formula

Slope (m) = 66-15/90-21

m = 51/69

m = 0.739

m is approximately 0.74
